IMPROVEMENT IN THREAD-SPOOLING MACHINES.

Specification forming part of Letters Patent No.

189,673, dated April 17, 1877 application filed August 16, 1876.

To all whom it may concern:

Be it known that I, JOHN W. WEsT, of Boston, of the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Machinery for Spooling Thread and do hereby declare the same to befully described in the following specification and represented in theaccompanying drawings, of which- Figure 1 is a top view, Fig. 2 a rearelevation, and Fig. 5 an end view, of a machine embodying my invention.

On the 10th day of March, of the year 1876, I filed in the United StatesPatent Office an application for a patent for improvements on machineryfor spooling thread. After due examination, such application was passedand allowed on the 13th day of May following.

To the machine described in the specification of the said application,and which is substantially represented in the above-mentioned drawings,1 have, in carrying out my'present invention, made certain additions, asfollows First, a skein-reel and a friction mechanism; second, anautomatic stop motion or mechanism to stop the machine on its completionof the load of a spool.

Heretofore, so far as I have been able to learn, it has been customaryto reel the skein and subsequently wind upon a bobbin the thread fromthe skein, the thread being afterward taken from the bobbin directlyinto the spoofing-machine or to its guide, and thence to the spoolarranged on the arbor of the machine. By my present invention I save theintermediate operation of winding the thread upon the bobbin, ordispense with such and the bobbin, as I combine the reel directly withthe machine, and apply to such reel a friction apparatus or mechanism,which will arrest the revolution of the reel on a stoppage of themachine. The machine being provided with a tension apparatusindependently of the said friction apparatus of the reel, the thread isnot only estopped from running off too freely from the reel, and kinkingin consequence thereof, but it is delivered to the spool under a properdegree of tension.

On account of the great momentum generated in the skein and reel in theprocess of unwinding the skein, it has been deemed practicallyimpossible to run the thread directly from the reel into thespoofing-machine, as, in stopping the latter, the velocity of the reel,together with its weight, would cause breakage and snarling of thethread, all of which I avoid by the friction apparatus, whichcounterbalances the momentum of the reel and stops such reel when themachine stops.

In the drawings, the spoofing-machine is represented at A, B being itstubular rotary arbor; b, the driving-pulley thereof; 0, the spindle,that slides lengthwise within the arbor; D, the furcated lever for thespindle; F, the knobbed slide-rod, to which the lever is jointed.

f is the notched guide, and y the vertical supporting slide-rod thereof,the latter being extended down through a guiding-standard, m, fixed to acarriage, G. The rod 9 is also secured to a rectangular frame, H,arranged to slide vertically in another carriage, l, which in turn issupported on parallel and horizontal rails, so as to be capable of beingmoved rectilinearly.

p p are the slotted guides of the frame H.

M M are the movable poppets, connected by levers and screws 8 s with theguides 10 p.

R S are screws upon one shaft with a bandpulley, Q. The threads ofonescrew are pitched in a direction opposite to that of the threads of theother screw.

A lever, T, pivoted at its middle to the carriage G, has at its endsfemale-screw projections, to engage with the screws It S, all of which,together with other parts of the spooling-machine, I have fullydescribed in the specification of my said application for a patent.

In carrying out my present invention I apply to a furcated standard, A,projecting up from the frame of the spoofing-machine, a skein-reel, B,arranged as shown, it being composed of an axle, a, and a series ofpairs of radial arms, I) b, extending therefrom. The axle has itsjournals supported in the standard A. The said axle is groovedtransversely to receive a cord, 0, which, attached at one end to thestandard, extends in the groove, and more or less around the axle, andhas a weight, I), fixed to its lower end. The cord and weight, with thegroove in the axle, serve as a friction mechanism to arrest therevolution of the reel on stoppage of the machine.

When the reel is in use, it has each pair of its arms connected by apiece of cord or twine, which serves to support the skein arrangedbetween the arms. The thread from the skeinreel is to be led under thetension-spring i, and thence through the perforated guide It, and to andinto the notched guide f, and thence to the spool on the spindle U. Ascrew for regulating the tension or the pressure of the spring '1: onthe thread goes through the spring, and screws into the guide It, suchscrew being shown in the drawing.

Furthermore, there is pivoted to the cartriage G a ratchet-Wheel, E,provided with studs 0, projecting from its inner side. (See Fig. 4,which is an edge view of such wheel.) A spring, F, fixed to the frame,and arranged as represented, bears upon the periphery of theratchet-wheel, and is provided with acatch, (1, extended from it, asshown. (See Fig. 5, which is an edge view of the spring.) There isarranged upon one of the parallel rods n n, which support the carriageG, a slide, G. Through a projection, e, therefrom a headedscrew-bolt,j", provided with the nuts 9 h, is extended, all being asshown, particularly in Fig. 6. A belt-shipper lever, II, pivoted to thecarriage I, has its shorter arm disposed between the bolt-head and thenext adjacent nut. The longer arm of the said lever is to be suitablyapplied to or connected with the belt for driving the pulley b, to becapable of moving the said beltfrom a driving-pulley to and upon a loosepulley, or vice versa.

The nuiuber of teeth in the ratchet-wheel regulates the number of layersof thread to be wound upon a spool, one of said layers being so woundduring each rectilinear movement of the carriage G. The ratchet-wheelshould turn on its pivot with sufficient friction to prevent such wheelfrom being revolved by the spring while the latter may be slipping onthe wheel. In each movement of the carriage in one direction theratchet-wheel will be partially revolved by the catch of the spring,such ratchet-wheel remaining at rest while the carriagc may be moving inthe opposite direction. In each half-revolution of the ratchet-wheel oneof its studs will be borne against the slider G, and will move such onits rod nin a manner to so move the shipper-lever H as to cause it toeffect or aid in efi'ecting the shitt ing of the driving-belt from thefast to the loose pulley, in order to cause stoppage of the machine oncompletion of a load on the spool.

I do not claim the combination of a rotary reel and a friction brake ormechanism applied thereto, with a machine for balling yarn, all being asshown in the United States Patent No. 165,978, such machine beingunprovided with any additional means for regulating the tension of theyarn while being Wound upon a bobbin by the flier of such machine.

What I claim as my invention is as follows:

1. The combination of the reel B and its friction mechanism with thetliread spooling machine A, provided with the guide it andtension-spring i, essentially as set forth.

2. The combination of the stop-motion with the yarn-spoolin g machine A,such stop-motion consisting of the ratchet-wheel E, its studs 0, thespring F, its catch d, the slide G, the screw-bolt f, nuts g h, and theshipperdever H, all being arranged and applied to the machinesubstantially as specified.
